Article
Full-text available
Numerous tsunami numerical models have been proposed, but their prediction accuracies have not been directly compared. For quantifying the modeling uncertainties, the authors statistically analyzed the prediction results submitted by participants in the tsunami blind contest held at the 17th World Conference on Earthquake Engineering. The reproduci...

The aim of this work is to validate and analyze with the numerical model OpenFOAM, the nonlinear interaction of a WEC under regular waves using the Overset framework. Previous techniques, such as deforming grid approaches, present problems to handle large body motions when modelling wave-structure interactions. Therefore, by means of the Overset me...

Full-text available
There are coastal areas which are particularly prone to landslide-generated tsunami risk. The destructive effects caused by the impulsive waves, generated by landslide sources, can be strongly magnified by the characteristics of the so-called "confined geometries" (e.g. bays, reservoirs, lakes, volcanic islands, fjords, etc.). Complicated physical...

Full-text available
The use of CFD for numerical representation of laboratory wave flume and basins, commonly known as numerical wave tanks (NWT), has become more popular in recent years with the aim of improving knowledge in the field of wave-structure interaction (WSI), both fixed and floating, due to advances that have been made in numerical modelling, mainly with...
Article
In this work, we present several applications of the 2D-3D multi-domain couplings for Navier-Stokes models developed and validated in its companion (Di Paolo et al. (0000), submitted). The methodology is used to carry out some relevant simulations which include long regular and irregular waves, solitary wave propagation on a shallow foreshore, focu...

Article
This paper and its companion (Di Paolo et al. (b), submitted) present near-far field coupling schemes of Navier-Stokes (NS) equations for high-fidelity numerical modelling of wave generation, transformation and interaction with structures. The computational domain is subdivided into near and far field zones (2D and 3D subdomains, respectively) in w...

Abstract The accurate modelling of the landslide‐generated tsunami characteristics in the so‐called near‐field is crucial for many practical applications. In this paper we present a new full‐3D numerical method for modelling tsunamis generated by rigid and impermeable landslides in OpenFOAM® based on the Overset mesh technique. The approach has bee...
Conference Paper
Full-text available
SE@PORT project aims to improve the overall performance of a single Wave Energy Converter (WEC), developing hybrid systems that combine the use of two technologies over and above individual working principles. An oscillating water column (OWC) and an overtopping converter (OBREC-type in this case) have been designed to be included in Las Palmas har...
Presentation
In recent years, the increase of computational resources make numerical models for studying real fluid-structure interactions very popular.Thus, strong, robust and accurate numerical tools are needed to solve problems more efficiently.Movable structures like wave energy converters (OWC) or floating offshore wind turbines (FOWT), moored ships or flo...
Conference Paper
In this paper we present a new method for numerically modelling landslide-generatedtsunamis in OpenFOAM® by using a new approach based on the Overset mesh technique. This technique, which is based on the use of two (or more) numerical domains, is new in the coastal engineering field and appears to be extremely powerful to model the interaction betw...
Article
Historic coastal structures have played a key role in small- to medium-size ports, being the driving force for the local development of coastal communities. Because coastal managers require reliable risk-based analysis of the whole life cycle of these coastal structures, previous lifetimes should be studied. This is a differentiating factor with re...
Presentation
In recent years, there has been an increasing interest in modelling floating structures in marine environments. A considerable amount of research has been done in the fields of renewable energy, naval engineering and oil-gas industry. Movable structures like wave energy converters (OWC) or floating offshore wind turbines (FOWT), moored ships or flo...

Numerical modelling of the interaction of water waves with coastal structures has continuously been among the most relevant challenges in coastal engineering research and practice. During the last years, 3D modelling based on RANS-type equations, has been the dominant methodology to address the mathematical modelling of wave and coastal structure i...

Conference Paper
Numerical modelling of floating bodies is still being a very challenging issue, especially for large body displacements. Despite of the good performance of potential flow models in predicting floating body dynamics, there are still physical processes which are not well reproduced with that approximation. Their strong assumptions yield a lack of acc...

Coastal infrastructures are particularly vulnerable to climate change effects. Ports and harbours, among them, will be especially affected because of their inherent long-life cycles, the high exposure of coastal localizations, the global market dependency, and the pre-established and very restrictive downtime thresholds. Expected sea level and storm energy rise, will change the structural and hydrodynamic response of actual harbours. This is especially important since traditional harbour design does not take into account the dynamic response of the structure along its life-cycle. This project will quantify the previously mentioned climate change effects on harbour structures, focusing on rubble-mound breakwaters, in order to obtain variation of failure probability due to climate change. The objective of the project is to contribute with an important improvement to the current state-of-the art, including an innovative coastal structure vulnerability and risk assessment. BRACC Project is supported by the Spanish Ministry of Economy, Industry and Competitiveness.
